Take a San Francisco rock tour

And then, of course, there's the Fillmore. Dennis McNally, the former aide-de-camp of the Grateful Dead and their authorized biographer, stands in the Fillmore's "Poster Room.'' The Fillmore is the virtual Vatican of rock ballrooms, - a 1,000-plus-capacity site run by famed promoter Bill Graham in the late 1960s, then closed, and then reopened in 1994 . Guests can pick from a barrel of apples in the front hallway (a Graham tradition), and everyone gets a free poster from the night's event.
